A return force and a balance counterweight are provided the double carrier element.

Description

Prismenfernrohr- mit Bi Idstabi lisierungPrism telescope with image stabilization
Die Erfindung betrifft ein Fernrohr mit kardanisch gelagertem Umkehrprismen"-*- System, wobei der .Lagerdrehpunkt von der Objektiv- und Okularebene gleichen Abstand hat.The invention relates to a telescope with a gimbal-mounted reversing prism "- * system, the bearing pivot point being at the same distance from the objective and eyepiece planes.
Die optische Leistungs ähigkeit von Fernrohren wird durch Vibrationen, die während der Benutzung des Fernrohres auftreten, stark beeinträchtigt.. Die Beeinträchtigung macht sich umso stärker bemerkbar, je höher die Vergrößerung des Fernrohres ist und führt zum Zittern des Bildes in der Bildebene des Fernrohres.The optical performance of telescopes is greatly affected by vibrations that occur during the use of the telescope. The impairment becomes more noticeable the higher the magnification of the telescope is and leads to the image trembling in the image plane of the telescope.
In der DE-PS 318227 wird eine Vorrichtung zum Ausgleich von Erschütterungen von Ferngläsern beschrieben, bei dem ein optisches System bei schnellen Dreh¬ bewegungen des Gehäuses Relativbewegungen zu den anderen optischen Systemen ausführt. Diese Schrift enthält einen Hinweis, daß mit der beschriebenen Vorrichtung auch zwei Fernrohre zu einem binokularen Fernrohr verbunden sein können, bei dem die Drehpunkte der Lager für die Umkehrprismensysteme die beiden Normalen zu den nicht zusammenfallenden optischen Achsen halbieren und bei dem die beiden Umkehrprismensysteme über ihre Träger verbunden sind. Nachteilig bei diesen Fernrohren ist, daß sie einen erheblichen mechanischen Aufwand erfordern und in binokularer Ausführung sehr voluminös sind.DE-PS 318227 describes a device for compensating for vibrations from binoculars, in which an optical system executes relative movements to the other optical systems when the housing rotates rapidly. This document contains a note that two telescopes can also be connected to a binocular telescope with the device described, in which the pivot points of the bearings for the reversing prism systems halve the two normals to the non-coinciding optical axes and in which the two reversing prism systems via their carriers are connected. A disadvantage of these telescopes is that they require considerable mechanical effort and are very bulky in the binocular version.
In der DE-OS 24 19532 wird eine Bild-Stab lisierungsvorrichtung offenbart, bei der ein B.i Idumkehrprisma kardanisch so gelagert ist, daß der Drehpunkt von der Objektivhauptebene und der Okularhauptebene gleichen Abstand hat. Das gleiche trifft zu für das in der DE-AS 23 53101 beschriebene Fernrohr mit Bi Idstabi lisierungo Bei diesen Fernrohren mit Bildstabilisierung ist es aus räumlichen Gründen nicht möglich, das Fernrohr in einer gebrauchs¬ günstigen Gestaltung binokular auszuführen.In DE-OS 24 19532 an image stabilization device is disclosed in which a bi-id reversal prism is mounted gimbally so that the fulcrum has the same distance from the main lens plane and the main eyepiece plane. The same applies to the telescope with image stabilization described in DE-AS 23 53101. With these telescopes with image stabilization, it is not possible for spatial reasons to design the telescope in a binocular configuration that is favorable for use.
Der Erfindung liegt die Aufgabe zugrunde, eine räumliche Anordnung für die Lagerung des Umkehrprismensystems eines Fernrohres anzugeben, die es gesta tet, mit geringem Aufwand auch bei einem binokularen Fernrohr eine Bild¬ stabilisierung zu erreichen.The invention has for its object to provide a spatial arrangement for the storage of the reversing prism system of a telescope, which allows the image stabilization to be achieved with little effort even with a binocular telescope.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Umkehrprismen***-- systeme zweier zu einem binokularen Gerät verbundener Fernrohre an einem kardanisch gelagerten, symmetrischen Doppelträger befestigt sind, der über eine Achse mit einem gehäusefesten, unbeweglichen Träger verbunden ist.This object is achieved according to the invention in that the reversing prisms *** systems of two telescopes connected to form a binocular device are fastened to a gimbal-mounted, symmetrical double support which is connected via an axis to a fixed, immovable support.
Vorte lhafterweise sind für den beweglichen Doppelträger Mittel zur Ausübu einer Rückstellkraft und ein Gegengewicht zur Gleichgewichtseinstellung vo gesehen.Advantageously, means for exerting a restoring force and a counterweight for adjusting the equilibrium are seen for the movable double carrier.
Zur Einstellung des Augenabstandes des Benutzers können vor den Okularen an geordnete, drehbare rhombische Prismensysteme vorgesehen sein.In order to adjust the eye relief of the user, orderly, rotatable rhombic prism systems can be provided in front of the eyepieces.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß mit einem vertretbaren Kostenaufwand und mit annehmbarer räumlicher Ausdeh nung ein binokulares Fernrohr mit Bildstabilisierung gebaut werden kann. Da Doppelfernrohr ist leicht ausführbar, da es für das Trägersystem nur ein kardanisches Lager erfordert.The advantages achieved by the invention are, in particular, that a binocular telescope with image stabilization can be built at a reasonable cost and with acceptable spatial expansion. The double telescope is easy to carry out since it only requires a gimbal for the carrier system.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigtAn embodiment of the invention is shown in the drawing and will be described in more detail below. It shows
Fig. 1 ein Ausführungsbeispiel des erfindungsgemäßen binokularen Fernrohre in perspektivischer Darstellung.Fig. 1 shows an embodiment of the binocular telescopes according to the invention in a perspective view.
Mit 1,1' sind die Objektive, mit 2,2' die Okulare und mit 3,3' die Umkehr- prismensysteme des dargestellten binokularen Fernrohres bezeichnet. DieThe objectives are denoted by 1.1 ', the eyepieces by 2.2' and the reversing prism systems of the binocular telescope shown by 3.3 '. The
O P WIP durch die Objektive definierten optischen Achsen tragen die Bezeichnung 4^4" und die durch die Umkehrprismensysteme 3,3' definierten optischen Achsen die Bezeichnung 5,5'. Die durch die Okulare definierten Achsen tragen die Bezeichnung 5a,5a'.OP WIP optical axes defined by the objectives have the designation 4 ^ 4 "and the optical axes defined by the reversing prism systems 3,3 'have the designation 5,5'. The axes defined by the eyepieces have the designation 5a, 5a '.
Der Prismenträger 6 ist beweglich und in zwei Richtungen drehbar gelagert; seine Lagerstellen 7 und 8 und die Achse 17 sind in der Abbi Idung sichtbar. Mit 9 ist ein gehäusefester, unbeweglicher Träger bezeichnet. Die Befesti¬ gung des Trägers 9 am Gehäuse ist in der Darstellung nicht gezeichnet. Sie kann beispielsweise über eine Schraubverbindung erfolgen. In Richtung der Y- und Z-Achse ist der Prismenträger 6 vom Fernrohrgehäuse entkoppelt. Da er in diesen Richtungen drehbar gelagert ist, kann er räumlich fest in Be¬ zug auf eine bestimmte Ausrichtung stehen bleiben, wenn das Fernrohr sich um die Y- oder Z-Achse infolge einer Vibration bewegt. Die Rückstellfeder 10 bewirkt die rasche Kompensation der infolge Vibration des Fernrohrs er¬ folgten Auslenkung des Trägers 6. Eine genaue Gleichgewichtseinstellung des Trägersystems ist durch das Gegengewicht 11 möglich. Die rhombischen Prismen 12,12' sind zur Einstellung der Pupillendistanz des Benutzers durch Änderung des Okularabstandes in Richtung 13,13' drehbar.The prism carrier 6 is movable and rotatably mounted in two directions; its bearings 7 and 8 and axis 17 are visible in the figure. With 9 a fixed, immobile carrier is designated. The attachment of the carrier 9 to the housing is not shown in the illustration. It can be done, for example, via a screw connection. The prism carrier 6 is decoupled from the telescope housing in the direction of the Y and Z axes. Since it is rotatably mounted in these directions, it can remain spatially fixed with respect to a certain orientation if the telescope moves around the Y or Z axis as a result of vibration. The return spring 10 rapidly compensates for the deflection of the carrier 6, which occurs as a result of vibration of the telescope. A precise equilibrium adjustment of the carrier system is possible with the counterweight 11. The rhombic prisms 12, 12 'can be rotated in the direction of 13, 13' to adjust the pupil distance of the user by changing the eyepiece distance.
Das gezeigte Ausführungsbeispiel der Erfindung weist eine einfache mecha¬ nische Lösung der Bildstabilisierung bei binokularen Fernrohren auf, die nur eine, beiden Umkehrprismensystemen gemeinsame, Lagerstelle erfordert. Allerdings läßt diese Ausführungsform Stabilisierungsfehler höherer Ordnung zu, die jedoch für den normalen Gebrauch vernachlässigt werden können. Die Richtwirkung wird durch eine Blattfeder und die Dämpfung der Bewegung durch ein in luftgedämpftes Gegengewicht ausgeübt. Für die Lösung der Aufgabe ist es auch möglich, andere aus dem Stand der Technik bekannte Mittel für die Richtwirkung und die Dämpfung zu verwenden. So können beispielsweise zur Richtwirkung Schrauben- oder Spiralfedern, oder ein Regelkreis mit Stellungs- indikatoren und einem elektromagnetischen Stellglied verwendet werden und zur Dämpfung der Bewegung viskose Flüssigkeiten oder eine Wirbelstromanord¬ nung.The exemplary embodiment of the invention shown has a simple mechanical solution for image stabilization in binocular telescopes, which requires only one bearing, common to both reversing prism systems. However, this embodiment allows higher-order stabilization errors, which, however, can be neglected for normal use. The directional effect is exerted by a leaf spring and the damping of the movement by an air-damped counterweight. To solve the problem, it is also possible to use other means known from the prior art for the directivity and the damping. For example, coil or spiral springs or a control circuit with position indicators and an electromagnetic actuator can be used for the directional effect and viscous liquids or an eddy current arrangement for damping the movement.
